In a 20 October 2026 statement, Defra and the Environment Agency said chief executives from affected water companies had been called before the National Drought Group to account for the steps being taken to protect customer supplies. The intervention followed the government’s decision to require daily monitoring of reservoir and river levels after severe drought was declared on 15 October in parts of Cornwall, Devon, Dorset, Somerset, East Sussex and West Sussex. Customer supplies remain uninterrupted, but the response has clearly moved into a more intensive regulatory footing. (gov.uk) The immediate measures reported to ministers are practical rather than symbolic. Water companies said they were reducing releases from reservoirs into local rivers where permits allow, managing water pressure overnight where appropriate, accelerating leak detection and moving water around their networks to support the lowest reservoirs. Defra’s position is that public supply must come first while the drought response is being stepped up. (gov.uk)
The key point for households and local institutions is that a severe drought declaration is not the same as an immediate loss of supply. The Environment Agency says severe drought is the highest drought classification and signals that exceptional action is needed to protect people, water supplies, the environment, farming and other essential services. It does not automatically trigger new restrictions or constitute a civil emergency, but it does authorise a more coordinated and interventionist response across government, regulators and water companies. (environmentagency.blog.gov.uk) That shift is now backed by a formal ministerial direction. On 15 October 2026, Emma Hardy issued a direction under section 40 of the Environment Act 1995 requiring the Environment Agency to prioritise protection of public water supply in the specified severe drought areas around Wimbleball, Ardingly, Roadford and Colliford reservoirs. The direction allows the agency, where necessary, to support temporary reductions in environmental releases and changes to abstraction constraints so that more water remains in storage, while also requiring evidence, enhanced monitoring, mitigation and frequent review. It must be reviewed monthly and expires when severe drought status is lifted from all specified areas. (gov.uk)
Some of the most concrete changes are already visible in the permit system. Defra said the Environment Agency has granted drought permits to South West Water and South East Water so they can reduce the amount of water released from Wimbleball reservoir into the River Exe and from Ardingly reservoir into the River Ouse. In Cornwall, temporary pumps have been installed to help move water around the area supplied by South West Water’s Stithians reservoir, and Wessex Water is preparing seven further drought permit applications that the agency says it will prioritise on receipt. (gov.uk) For policy and operations teams, this is the clearest indication of what severe drought means in practice. The state is not taking over day-to-day supply management, but it is directing the regulator to move faster, accept tighter operational trade-offs and keep companies under close scrutiny. Water companies remain legally responsible for maintaining supply, yet the government is now setting the terms of the response with daily monitoring and stronger reporting expectations. (gov.uk)
The next live decision concerns business restrictions rather than household interruption. Defra said applications from South East Water, South West Water and Southern Water for non-essential use bans are under consideration by the Environment Secretary. Under the Environment Agency’s drought framework, those bans sit within the drought order regime and allow limits on further non-domestic uses of water; they are separate from temporary use bans, formerly known as hosepipe bans, which companies can introduce under their own powers. (gov.uk) That distinction matters for employers, public bodies and larger site operators in the affected areas. A non-essential use ban is not yet in force on the basis of this statement, but ministerial consideration means the government is actively testing whether extra demand controls on some business activity are justified. In regulatory terms, that is a more serious stage than general public messaging alone. (gov.uk)
The accountability structure around the response is also widening. Defra said the National Drought Group, which includes the Met Office, government departments, regulators, water companies, the National Farmers’ Union, the Canal & River Trust, anglers, hydrologists and conservation specialists, has been meeting regularly since August to coordinate the national response and hold organisations to account. Alongside that national structure, Local Resilience Forums in the severe drought areas have begun enhanced engagement to coordinate local risk assessment and preparedness. (gov.uk) For councils, emergency planners and regulated operators, the message is straightforward: drought plans are expected to translate into visible action. The Environment Agency has said companies must move quickly on leakage, customer communications and early applications where extra restrictions may be needed. The formal direction also requires close working between Defra, the affected companies and Local Resilience Forums, together with reporting on the measures taken, the water retained for public supply and the environmental effects that follow. (gov.uk)
The wider hydrological position explains why ministers have moved now. In its weekly drought report covering 9 to 15 October, the Environment Agency said national reservoir storage had fallen to 54% of capacity, around 21% below the long-term average for the time of year. Eighteen reservoir groups were below 50% full and 11 were classed as exceptionally low. The same report confirmed the severe drought declaration on 15 October, while Defra said the South East and South West had recorded their driest April-to-September period in more than a century, with particular pressure around Ardingly and Wimbleball. (gov.uk) There is some prospect of short-term relief, but not yet a route out. The 20 October government statement said wetter weather was expected later in the week, while Environment Agency chief executive Philip Duffy and Met Office business manager John Loynd both warned that the drought was far from over and that it was too early to know whether the rainfall would materially change the position. The Environment Agency has said some areas need at least 120% of average rainfall over the next six months for the country to be considered out of drought by the start of spring, and its 15 October briefing said 82% of England remained in drought. (gov.uk)
Environmental protections have not been set aside, but they are being managed under tighter pressure. Defra said fish rescue plans are being prepared in case reservoir levels fall further, and the ministerial direction explicitly states that the Environment Agency’s statutory duties, including environmental protection, still apply. Any use of regulatory discretion must be proportionate, evidence-based, supported by enhanced monitoring and mitigation, and reversed when severe drought status ends. (gov.uk) The immediate issues to watch are therefore procedural as much as meteorological: decisions on pending non-essential use bans, submission of further drought permits, the continuation of daily monitoring and water quality checks, and the monthly review of the section 40 direction. For the public, the present position remains continuity of supply with a strong official request to reduce use. For government and operators, the test is whether early intervention now is enough to avoid harsher restrictions later in the winter. (gov.uk)
